What is the color of a star (a) with B magnitude of 8.122 and a V magnitude of 8.284?
(b) with B magnitude of 2.364 and a V magnitude of -0.593?
(c) with B magnitude of 7.495 and a V magnitude of 5.831?

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

i believe the answer is electric potential.

explanation:

i dont have a visual in front of me, but i can you reason to try to get the right one. the graph should look like this, 0 to 6 there is a spike, 12 to 14 there should be a very low point. slight increase in the graph at 12 to 14, and flat 14 to 18
